The line comes from Diablo, Blizzard's 1996 action role playing game, where The Butcher is an early boss encountered in the cathedral dungeon beneath Tristram. His only spoken line on seeing the player became one of gaming's most quoted boss introductions, repeated in later Diablo games and remasters. Clips of the growl spread through forums, streams and meme edits because it sums up a boss fight in two seconds. It remains popular with horror and retro gaming creators who grew up fearing that first encounter.
